[mpas-developers] Zoltan support in MPAS

[Michael Duda]

Hi, All.

The MPAS framework currently has a number of hooks to call the Zoltan 
package to reorder cells, edges, and vertices in an attempt to improve
cache reuse; however, the code does not currently build with Zoltan,
and I suspect it has been a couple of years since anyone has tried to
do so. In the interest of clearing out unused or unusable code ahead of
the initial MPAS release, I'd like to propose the idea of eliminating
all of the Zoltan hooks in the MPAS code. Should there be any interest
in future in trying out Zoltan, I think it would probably be a good 
idea to re-implement the functionality from scratch anyway to better
fit with our current initialization sequence. What do you all think
about getting rid of the Zoltan code in MPAS?

Regards,
Michael
